This invention relates particularly to such wheels and axles asare. adapted. to form. parts of mine cars or similar cars;

The object of the invention is. to. provide an efiicient and: durable wheel structure. sur

ring, C2,v looselysurrounds the-journal and extends into the grooves", 61. i h

- From av little beyond". the outer or right hand. ends: of the rollers, G, (as shown in Fig;

1') the-hub, B1, has an outwardv extension, B 3, whose interior: diameter is a little larger than the interior diameter of the main part of the hub; Thus there is formed an annular shoulder, B16, near: the: ends; of the rollers andfac-ing outward or'towardthe right;

Near the end ofthe journal, A, is a trans verse aperture, A1 which receives a cross-pin or cotterpin,:G having a head, G1, larger than the aperture,-Al. The'lower end ofthe cotter pin is slotted and spread to form arms, G2, which prevent the cotter pin from moving upward in the journal. Between the cotter pin. and the. adj aeentiends ofthe rollers, C, is washer", F2, lying against" the cotter pin. Atithehead, G12, of'the cotter pin, said Washer is slottedto. form" tongues, F3, bent laterally to places-one tongue against each side of said head, whereby the washer isiheldimmovably on the journal. Betweenthat washer and'the ends'of the rollers: is'a ring-form plate, F, which lies agai'nstfthe washer, F2, andagainst the hub shoulder, B6. on the periphery of the plate, are'twof diametrically. opposite notches, F 1, which'receive inward extensions, B7, of thefhub' wall". Thus the plate, F, is engaged to be rotated with the hub. Said notches, F1, are made deeper than the wall extensions, B7 whereby apassage is formed for the passing of lubricant, as will'be described further' on.

A cap, E, (shown in detail in Figs. 1, 9 and 10.). fitsslidablyinto the interior ofthe hub extension, B3,.and has a flange, E3, which bears against a gasket, E4, composed of elastic material and lying against the rim of the flange, Said gasket lies against the ring-form plate, F. When the cap, E, is pressed. toward. the right, as. viewed in Fig.

1, the gasket, E4:,.is pressed against the. plate, F, whereby said plate is. pressed against the hub shoulder, B6.

A screw, E6, extendsthrough the hub wall, B3,. into a horizontal groove-,EZ, in the cap, E,.,te compel rotation of .thecap with the hub.

Said groove allows limited horizontal movement of the cap.

The cap, E, has on its axial line a chamber, E1, adapted to receive a polygonal nut, N, the sides of the chamber being formed to engage the nut, whereby the nut is held against rotation independently of said cap. From the chamber, E1, ducts, E2, lead to and through the inner face of the cap, E. Those ducts serve to conduct lubricant to the interior of the cap, as will bedescribed further on.

Along the outer face of the cap, E, the inner face of the hub walLBS, is provided with channel. B5, which receives the end edges of the locking plate, H. (Figs. 1, 6, 7, 9, 10 and 11.) Said plate has two opposite parallel edges. H1. Between those edges are end edges. H2. concentric to the axial line of the an. E, and the hub; and the length of said plate is snflicient to bring the edges, H2. into the channel, B5. when said plate is in working position on the hub. The channel, B5,is so positioned as to cause the locking plate to bear against the adjacent upright face of the cap. E. and at the same time bear against the outer or right hand channel wall. The cap, E.-has in itsouter face a recess, E5. as wide s the width of the lockingplate and as deep as. e thickness of that plate.

The ocking platehas a central aperture,

v-"3.-wh ch is smaller than the chamber, E1. Hence the nut, N, isretained in the recess or hamber. E1. when the locking plate'is in position. Between the nut and the locking plate, a se ling gasket, H4. surrounds the aperture. H3. the gasket being pressed between the'locking plate and the'nut. The ocking plate is to be made sufficiently flexible to allow it to be sprung to force its end edges. H2, into the channel,rB5. Since the ad acent end of the cap, E, is close to the channel. B5. the locking plate offers large resistance to the outward movement of the cap, the outer face of the channel forming an abutment against-which the cap presses the outer part of the locking plate. When the locking plate has been put into position, any suitable closing mem er may be extended through the aperture, H3. of the locking plate and into the nut for closing the passage through the nut to the lubricant ductr-s, and drawing the nut against the gasket, H45. The part of the closing member outside the locking plate is to have a shoulder to engage the locking plate for limiting upward movement of the closing member. Such closing member is preferably a grease screw. Lot well-known form, said screw being adapted to receive connection with the discharge member of a lubricant serving device, sometimes called a grease gun.

When the locking plate is to be'removed for releasing the cap, E, as a preliminary to removing the wheel, the grease screw or other closing member is removed and a bolt, J, substituted (Fig. 8), the bolt being rotated sulficiently to cause the threaded end of the bolt to press against the face of the cap, whereby the nut is forced outward against the locking plate sufficiently to spring said plate un til the end edges of the locking plateare released from the channel, B5.

, The middle, inner part of the inner face of the cap, E, is made convex so as to adapt it to bear against the central part of the end face of the journal; and said part of the cap is Fchilled to make it hard, whereby it is adapted to resistwear during rotation of the hub in contact with the journal.

It will now be noted that endwise thrust of the axle journal toward the right, as shown in Fig. 1, will be taken by said convex face of the cap, E, and that thrust of the axle journal toward the left will be taken by the ringform= plate, F, and the washer, F2, and the cotter pin, G. During rotation when the axle thrust is toward the left, the friction incident to such rotation is taken by the washer, F2, and the adjacent faces of the ring-form plate, F, and the cotter pin, G. r Lubricant. is to be introduced through the grease screw, I, and thenut and the ducts, E2, in the cap, E. Thence the flow is around the end of the journal and the washer, F2, and through the notches, F1, of the ring-form plate, 'F, and thence into the spaces between the anti-friction rollers, C. In Fig. 4a and Fig. 8, the ducts, E2, are extended farther away from the axial line of'the cap.

Diametrically opposite each other and in the plane of the cotter pin, G, are apertures, B4, of sufficient size to permit the passing of the cotter pin when the cap, E, is not in posl- D tion inthe hub.

: For assembling, the hub lining, D, and the rollers, C, and the ring, C2, are placed into the hub and around the journal, A. Then the ring-form plate, F, and the washer, F2,

and the gasket, E4, are placed into position around the journal and within the hub. Then the cotter pin is inserted through one of the apertures, B4, into the transverse aperture, A1, in the journal. Then the cap, E, is moved into place through the outer end of the huh and the screw, E6, placed into position. Then the nut, N, and the gasket, H4, are put into position in the chamber,E1. Then the looking plate, H, is forced into position against the cap, E, with its curved end edges in the channel, B5. Then the retaining plug, I, preferably a grease screw, is insertedthrough the locking plate aperture, H3, and into the nut, N. For removing the wheel from the journal, the several steps above stated are reversed. To make springing of the locking plate easier and yet aflord suflicient strength at the curved edges, the grooved edges may be made thicker and the body of the plate made thinner,;as;sho.wmin In Eig.1l3,..theenr tire; plate. is: made relatively thin and the curved. edges. fielded oyer to; give desired thickness. andistrength.
